Dr. Sai Raghavapuram is an exceptional physician based on my interactions with him. His genuine and sincere approach immediately puts you at ease, creating a comfortable environment for open communication. He truly listens and takes the time to ensure you feel understood and cared for, making every interaction a positive experience.
Dr. Ton is the best primary physician I have ever had. She is very well trained. She recognized my earache as a symptom of arthritis when two others were at a loss. She is warm and caring, a wonderful person.
My visit to DHAT in Legacy - Frisco, was such an awesome experience. I met Dr. Sai during my visit, and he was very patient, professional, and relatable. Dr. Sai worked closely to ensure that I received the care that I needed. He takes time to listen to his patients, and equally answers all the questions that comes his way in a very personable manner. His doctor - patients professional relationship is top notch.
The administrative staff are also the best. They quickly called me to reschedule my appointment closer when another patient cancelled a previous appointment.
I highly recommend anyone who wants to experience quality healthcare attention with awesome patient care to visit this Frisco location and see Dr. Sai and his staff. They are awesome !

Dr. Sai Raghavapuram is an excellent doctor who truly cares about his patients. He explained everything thoroughly and made sure I felt at ease during the colonoscopy. A top-notch experience!
Great experience! I was in and out of there. I waited in the waiting room longer than I was in the back for the procedure. ALL of the staff was kind. Best first experience ever! Oh and the nap you get is one of the best 🤩.
Thank you to all staff!! Job well done. Dr. Maddala was very friendly. Definitely recommend

Great people providing great care in a very nice facility. 👍
I saw Dr Maddala today for a routine colonoscopy. This was my first time visiting her practice and I was extremely impressed with my experience. The person at the front desk (I forgot her name) was very friendly and efficient. Karen, the nurse who accompanied me through all the preparation was personable, professional and proficient. Her demeanor would put anyone at ease. Amber the anesthesiologist was the best ever and I’ve had many (over 15). Besides being excellent at her job, she was funny and I enjoyed joking around with her. Even though I only talked to her for a few minutes, Dr. Maddala was great too. I highly recommend this facility for any digestive health needs.
Professional staff and experienced doctor. Highly satisfied with the experience. Recommended.

Dr. Yamini was exceptional throughout the entire process. Their professionalism, knowledge, and empathetic approach made a significant difference. They took the time to explain the diagnostic results clearly and answered all our questions with patience and clarity. Dr. Yamini's and team’s dedication to patient care was truly commendable and greatly appreciated.
Overall, the experience was highly positive, and I wanted to extend my heartfelt thanks to everyone involved. Your hard work and commitment to providing top-notch healthcare services do not go unnoticed.

Dr Maddala is hands down the best GI doctor that I have seen since 2008. She is awesome! would definitely give her five stars and an A plus rating on health grades. She listens to her patients, has excellent bedside manner and puts the health of her patients at the forefront of everything she does. I highly recommend her to anyone experiencing and Gastrointestinal diseases or syndromes
Dr Sai and his team are amazing. After my testing I received detailed reports with his findings plus an explanation from him in person. The next day I received a text checking on me. Less than a week later Dr Sai contacted me with additional testing results himself. I can’t say enough positive things about this practice and Dr Sai.
Dr. SAI is awesome. I felt comfortable and well informed. He called me for a follow up to let me know everything was OK.
I received the absolute best care from Dr. Maddala and the team at Digestive Health Center of Allen! Check them out!
